Howard, J B

Work at MIT during this contract period has been concerned with kinetics and mechanisms of aromatics oxidation and soot formation in flames. The scope includes detailed measurements of profiles of stable and radical species concentrations and soot-particle number concentration and size distribution through the reaction zone of low-pressure one-dimensional premixed flames. Intermediate species identifications and mole fraction, flux, and net reaction rates calculated from the profile measurements are used to test postulated reaction mechanisms. The aromatics oxidation work is focused mainly on benzene, and the soot formation work is primarily concerned with the particle inception or nucleation stage. Particular objectives are to identify and to determine rate constants for the main benzene oxidation reactions in flames, and to characterize the soot precursor species and the mechanisms and kinetics of the transition from molecules to nascent soot particles. 6 refs., 1 tab.
